Thanks a bunch, I kind of figured it would be.. The .019 is one of the brightest I have ever used, I used my rheostat more then i thought I would...

You sure can, just did it to mine when i put my new strings on.. Just take the HHA cover off the wheel (2 screws) and loosen the screw that holds the wheel and do all the fine tuning you want...

Might have a .019 head available next week, if you interested send me a PM...

I guess I wasn't clear. I meant I was thinking about replacing the .019
OL5000 I have now with the .010. Can I just replace the scope and
windage bracket? I have the old style windage unit that has a threaded
rod to move the scope, (not toolless). If so how much does the scope unit run?

You might want to contact them on that question, they will tell you what you need to do.... From what my Pro shop guy told me is that it would be a quick change, i will let you know what I pay next week when it comes in....

I must not have that on mine. I'll look when I get home but don't remember anything over the fiber on the pin housing. Not all OL-5519's must come with the rheostat....guess I thought they did. Can it be added on?

I don't think your model comes with it but I would almost bet you could buy one direct from HHA?

I was actually looking at buying this site. After your review, I am going to get one. I was worried about the .010 not being bright enough in low light, but it does not seem to be a problem. Thanks for the review!

Rheostat Clarification...

The rheostat is standard on the OL-5510, OL-5519, OL-5500, XL-5510, XL-5519, XL-5500 and the same models in the DS (Ultra) Series. The aluminum sleeve simply threads over the fiber optic wrap and modifies the pin brightness as you expose more/less fiber. Unfortunately, for those with the 5000 Series, there is no way to just add the rheostat as the sight housing requires additional machining steps.

HAA for Elk?

I was thinking about using an HAA for elk in Sept. I am a little worried that the elk move too quick and I will be unable to adjust the sight in time. Would I be better off with a five pin fixed sight? I am looking for advise.

I ordered an OL5500 with the .010 pin and rheostat. I hope I can see it ok.
The pro shop guy said he looked at some brand of sight with the .010 pin
and he couldn't see it indoors at their range. Their range is pretty well lit.
I don't think it had 5' of fiber optic though.

Answer To Having Enough Time To Move A Single Pin Sight...

Having spent the past 13 years and close to 700 trips to the field with a one pin sight, I can honestly say that the sight has never cost me an opportunity on an animal. That being said, the majority of my hunting is for whitetails here in Wisconsin, on trails with most shots being 30 yards or less. I do hunt some larger food plots and field edges that offer longer shot opportunities as well. In those cases, the deer are generally relaxed, unaware of my presence, and offer plenty of time to range the distance and adjust the sight accordingly. The same could be applied to a western hunt for mule deer, elk, antelope, or any other long range game animals.

Ever increasing bow speeds have turned more people onto single pins the last few years. We've also noticed that many of our older hunters have gone to a one pin set up because of deteriorating eyesight. What once was four or five pins has become a blur and a one pin has solved that problem.

Hopefully this cleared up a few questions for those curious about the speed of adjustment of a one pin. Please feel free to contact us with any other questions.

What Chris said !!....The advantages of a single pin are many on a fast bow. No pin cluter, only having one pin to concentrate on, one setting out to certain yardage....I'm shooting right at 290 fps, I have MY OL5519 set in 5 yd increments from 20-40 yds....I leave it at 25yds and use 1 pin out to 32 yds, longer if needed just by using a little holdover....it is a awesome hunting setup.
In crunch time it is a win win for me not having to decide on how to split pins or them being to close .......it has worked for me for many many years.....

Was your bubble level spot on or did you have to compensate? I had to shim my HHA to get the bubble level with the bow. Great bright sight for sure.

My OL5519 also required the bubble to be leveled square to the bow. I set the bow up in my vise and accurately plumbed the bow string, in both axes. Then, after checking the bubble I tried different shims, repeating the plumbing routine for each trial until I finally ended up using a 0.020" spacer (same as used on cams) on the top mounting bolt. Now the bubble is square to the string. If there is a better way to do this, please let me know.

This is a great sight and the customer support by HHA (Chris) is outstanding!

Awesome sight for sure, I have the 5519 and just ordered the .010 housing today...

Now that sounds like an interesting thing to do. Have to think about that. Even though the 0.019" pin works well, I suspect the 0.010" pin would be even better at longer ranges for sighting in on smaller targets. Also, I think the new pins are blade pins and that would provide better filament support.

Chris, since I don't think I can just swap out pins in my existing OL5519, could please email me with a cost to buy a new housing with the 0.010" blade pin. If I can swap them out, please let me know.

Thanks.

I switched to the HHA last year and hunted with it exclusively last season... I was worried that adding another thing to do at the moment of truth was gonna be a pain, but it was a non issue..
I set mine at 25yds and was good from point blank to 30yds and it worked flawlessly..
Now where the site relay excelled, was out past 30 in which case i was not taking a hurried shot anyway...
When you have a deer that is feeding and is 36 yards away that you plan on shooting, there is no guess work. You simply adjust the dial to 36 and make the shot, you don't have to hold your 30 pin high or your 40 pin low.. being able to put my pin right on my target, right on my spot, has increased my effective range... No more guess work, you couple the HHA sight with a range finder and i guarantee you will me a more accurate hunter in the woods...
Best of luck this season..........

As usual Chris is right on the money! I previously had a 4-pin sight with 0.029" pins sighted in at 20/30/40/50 yds. I could shoot at 20 yds, but when using the other pins, especially in bright sunlight with my "older" eyes (approaching 67) I couldn't see the target as the pins blurred together. What a difference with the single 0.019" pin! I don't even need the rheostat, it's bright enough without it. And the single pin really avoids the "clutter" of multiple pins. Looking through only one pin is a great improvement!
